I sent my P229 .40 to the Sigarms Sigtech gunsmiths, right on the Sig website. They worked over the trigger, added adjustable combat sights, and honed the slide. It went from a marginal shooting pistol, to my go to gun for personal defense, due to the increased accuracy. When it was new I just could not get a decent grouping, not that I am a marksman by any means. But when it came back it was like a whole different pistol. It was easier to shoot, and I could shoot it far more accurately. It was worth every penny. If I remember right it was about $270 for all the work with shipping.

I had only put about 300 rounds through it before I sent it in. It may not have been broken in by that point...

About 500 rounds downrange and some dry firing has smoothed out every Sig I own. Sig tends to "overspring" their guns which makes for the tough DA trigger pull. Sig sights are also very easy to change out - nothing like XDs...
